The invention belongs to the technical field of wireless communication, and relates to a voltage-controlled oscillator, in particular to a coupling voltage-controlled oscillator based on a four-port coupling network. The coupling voltage-controlled oscillator is used for solving the problems that a traditional coupling voltage-controlled oscillator has the requirement for the symmetry of a coupling network, the coupling network is not prone to achieving absolute symmetry, the purpose of reducing phase noise cannot be achieved, and more area is occupied. According to the invention, the invention is composed of four identical voltage-controlled oscillators and a four-port coupling network, and a tail resistor is connected in series to a common-mode path to replace an LC parallel resonant cavity, so that the chip area is greatly reduced while the phase noise is effectively reduced. Moreover, a common mode point coupling mode is adopted, so that a coupling network is more symmetrical, wiring is shorter, mismatch is reduced, noise at a second harmonic position can be greatly reduced, and the possibility that phase noise is deteriorated due to the fact that the second harmonic noise is down-converted to the position near fundamental waves is reduced.
